秋令沟地区钨矿化特征分析及成因探讨

Analysis and genesis of tungsten mineralization in the autumn gully area

秋令沟地区钨矿小而富,同时伴生有一定数量的金、银和铜,具有一定的开采价值。本文从钨矿化特征、岩浆岩和构造条件三个方面分析,认为该地区钨矿化与燕山早期黑云母二长花岗岩体关系密切,钨矿的分布受挤压破碎带严格控制,较为发育的北西向裂隙为含矿热液输送提供了良好的通道和赋存空间。

The tungsten deposits in the autumn gully area are small and rich,accompanied by a certain amount of gold,silver and copper,which have certain mining value.From three aspects of tungsten mineralization characteristics,magmatic rocks and tectonic conditions,this paper holds that tungsten mineralization in this area is closely related to the early stage of the black mica two granitoid in Yanshan.The distribution of tungsten deposits is strictly controlled by the crushing zone,and the relatively developed northwestern fissure provides a good channel and storage space for the conveying of ore bearing hydrothermal fluid.
